GS8632C
GS8632C Available in SOP-8 Package
General Description
The GS8632C have a high gain-bandwidth product of 6MHz, a slew rate of 4.2V/μs, and a quiescent current of 470μA per
amplifier at 5V. The GS8632C is designed to provide optimal performance in low voltage and low noise systems. They provide
rail-to-rail output swing into heavy loads. The input common mode voltage range includes ground, and the maximum input
offset voltage is 3.5mV for GS8632C. They are specified over the extended industrial temperature range (-40℃ to +125℃).
The GS8632C dual is available in Green SOP-8 package.

Note:
Stress greater than those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these or any other conditions outside those indicated in the operational
sections of this specification are not implied. Exposure to absolute maximum rating conditions for extended periods may affect
reliability.
